How would you write an end to end test that checks a full user flow across multiple pages, such as logging in and viewing a dashboard?
AdvancedAnswer
Tools like Cypress or Playwright run your actual app in a real browser and simulate a real user's actions across multiple pages, such as typing into a login form, clicking submit, and checking that the dashboard page eventually shows the expected content, testing the entire flow exactly as a real user would experience it.
// A simplified Cypress test
cy.visit('/login');
cy.get('input[name=email]').type('user@example.com');
cy.get('input[name=password]').type('password123');
cy.get('button[type=submit]').click();
cy.url().should('include', '/dashboard');
cy.contains('Welcome back').should('be.visible');Real-world example A team writes an end to end test simulating a customer logging in and reaching their dashboard, catching a real bug where a recent change accidentally broke the redirect after a successful login, something a smaller unit test would not have caught.
